[466] And how does a bhikkhu generate zeal (chanda), endeavor, arouse energy (vīriya), exert the mind (citta), and strive for the non-arising of unarisen evil, unwholesome phenomena (dhammā)?
Therein, which are the unarisen evil, unwholesome phenomena? The three unwholesome roots (akusalamūla) — greed, hatred, and delusion (lobha, dosa, moha) — and the defilements (kilesa) standing together with them; the aggregate of feeling (vedanākkhandha), the aggregate of perception (saññākkhandha), the aggregate of volitional formations (saṅkhārakkhandha), and the aggregate of consciousness (viññāṇakkhandha) associated with them; and the bodily action, verbal action, and mental action originated by them — these are called unarisen evil, unwholesome phenomena.
Thus, for the non-arising of these unarisen evil, unwholesome phenomena, he generates zeal, endeavors, arouses energy, exerts the mind, and strives.
